This document contains some notes I have gathered while I was trying to setup a redis service using boot2docker running on OS X. This won't cover what Docker is, see Docker website for details.
First, install Virtualbox and follow the steps at http://docs.docker.com/installation/mac/
Since Docker only runs on Linux, boot2docker runs a virtual machine in Virtualbox (or VMWare etc), however you can run the docker command on OS X

| Ruby 2.1.0 in Production: known bugs and patches | |
| Last week, we upgraded the github.com rails app to ruby 2.1.0 in production. | |
| While testing the new build for rollout, we ran into a number of bugs. Most of | |
| these have been fixed on trunk already, but I've documented them below to help | |
| anyone else who might be testing ruby 2.1 in production. | |
| @naruse I think we should backport these patches to the ruby_2_1 branch and | |
| release 2.1.1 sooner rather than later, as some of the bugs are quite critical. | |
| I'm happy to offer any assistance I can to expedite this process. |
#The power of z
Do you spend lots of time doing things like this?
cd this/is/the/path/that/i/want/so/i/type/it/all/out/to/get/whereiwantWith z, you could just do this:
| # LBs have 8 cores. One is used for haproxy, rest are used for nginx workers | |
| worker_processes 7; | |
| worker_rlimit_nofile 90000; | |
| pid <PID_FILE>; | |
| events { | |
| use epoll; | |
| multi_accept off; | |
| accept_mutex off; |
| # put this piece of code in your spec/spec_helper.rb or spec/support/any_rb_file.rb | |
| # then run `rake spec` | |
